FIG 1 zeigt einen Kfz-Fensterheberantrieb mit einem einstückig spritzgegossenen, aus einem Getriebegehäuse 2 und einem Elektronikgehäuse 3 bestehenden einstückige Basisgehäuse, an das ein antreibender Kommutatormotor mit einem topfförmigen Motorgehäuse 1 mit seiner offenen Stirnseite angeschraubt ist. Die in das Getriebegehäuse 2 verlängerte Motorwelle 4 des Kommutatormotors treibt mit einer Schneckenwelle 41 in hier nicht näher erläuterter Weise ein Schneckenrad an, das z.B. mit einer Seilscheibe eines Seilzug-Fensterhebers gekuppelt ist.1 shows a motor vehicle window regulator drive with an integrally injection-molded, one-piece base housing consisting of a transmission housing 2 and an electronics housing 3, to which a driving commutator motor with a cup-shaped motor housing 1 is screwed with its open end face. The motor shaft 4 of the commutator motor, which is extended into the gear housing 2, drives a worm wheel with a worm shaft 41 in a manner not explained here, which, for example, is coupled with a cable pulley of a cable window regulator.

In das aus Getriebegehäuse 2 und Elektronikgehäuse 3 bestehende, topfförmig ausgebildete einstückige Basisgehäuse ist von der in FIG 1 nach oben offenen, noch nicht durch einen Deckel verschlossenen Montageseite eine in FIG 2 in Draufsicht bzw. in FIG 3 in perspektivischer Darstellung gezeigte Leiterplatte 5 eingelegt, die in ihrem in das Getriebegehäuse 2 reichenden Abschnitt einen Bürsten-Aufnahmeteil 51 und an ihrem rechten Abschnitt im Elektronikgehäuse 3 einen Anschlußstecker-Aufnahmeteil 52. Das Motorgehäuse 1 des Kommutatormotors ist axial derart verkürzt, daß der auf der Motorwelle 4 befestigte Kommutator 42 im Bereich des Getriebegehäuses 2 liegt.A circuit board 5 shown in FIG. 2 in plan view and in FIG. 3 in perspective is inserted into the pot-shaped, one-piece base housing consisting of gearbox housing 2 and electronics housing 3 from the assembly side which is open at the top in FIG. 1 and is not yet closed by a cover, which in its section extending into the gear housing 2 has a brush receiving part 51 and on its right section in the electronics housing 3 a connector receiving part 52. The motor housing 1 of the commutator motor is axially shortened such that the commutator 42 fastened on the motor shaft 4 in the region of the Transmission housing 2 is.

Wie insbesondere aus FIG 3 ersichtlich, dient die Leiterplatte 5 nicht nur als Aufnahme- und Kontaktierungsmittel für eine Bürstenhalterung 6 im Bereich des Bürsten-Aufnahmeteiles 51 und eines Anschlußsteckers 7 im Bereich des Anschlußstecker-Aufnahmeteiles 52, sondern auch zur Aufnahme und zum elektrischen Anschluß der Bauelemente einer Motorelektronik, wie z.B. eines einem Magnetrad 13 auf der Motorwelle 4 zugeordneten Hallwandlers 8 mit seiner vorteilhaften direkten Befestigung am Bürsten-Aufnahmeteil 51 , zweier Motorrelais 9, 9, eines IC-Bausteines 10, eines Thermowächters 11 und einer Drosselspule 12. Weitere von der Leiterplatte 5 aufgenommene Bauteile sind der Deutlichkeit wegen in der Darstellung weggelassen.3, the printed circuit board 5 serves not only as a receiving and contacting means for a brush holder 6 in the area of the brush receiving part 51 and a connector 7 in the area of the connector receiving part 52, but also for receiving and for the electrical connection of the components of motor electronics, such as a magnetic wheel 13 the Hall shaft 8 assigned to the motor shaft 4 with its advantageous direct attachment to the brush receiving part 51, two motor relays 9, 9, an IC module 10, a thermal monitor 11 and a choke coil 12. Further components picked up by the printed circuit board 5 are shown in FIG Representation omitted.

Zur elektrischen Kontaktierung der von der Leiterplatte 5 aufgenommenen Bauteile sind jeweils Lotanschlüsse 65 an der Bürstenhalterung 6, Lötanschlüsse 731 an den Steckern 73 des Anschlußsteckers 7, Lötanschlüsse 81 an Hallwandler 8, Lötanschlüsse 91 an den Motorrelais 9, 9, Lötanschlüsse 101 am IC-Steuerbaustein 10, Lötanschlüsse 111 am Thermowächter 11 und Lötstellen 121 an der Drosselspule 12 vorgesehen, die durch entsprechende Kontaktierungsöffnungen der Leiterplatte 5 durchgesteckt und auf deren Rückseite durch eine gemeinsame Schwallbadlötung untereinander bzw. mit Leiterbahnen 53 der Leiterplatte 5 elektrisch kontaktiert sind. Anstelle der beschriebenen Schwallbadlötung kann bei noch moderneren Fertigungsanlagen auch eine sogenannte SMT Technik mit oberflächenmontierbaren bzw. kontaktierbaren Bauelementen vorgesehen werden.For electrical contacting of the components picked up by the printed circuit board 5, solder connections 65 on the brush holder 6, solder connections 731 on the plugs 73 of the connector 7, solder connections 81 on Hall converter 8, solder connections 91 on the motor relays 9, 9, solder connections 101 on the IC control module 10, solder connections 111 on the thermal monitor 11 and soldering points 121 on the choke coil 12 are provided, which are pushed through corresponding contact openings in the printed circuit board 5 and on the rear side of which are electrically contacted by joint wave soldering with one another or with conductor tracks 53 of the printed circuit board 5. Instead of the described wave pool soldering, so-called SMT technology with surface-mountable or contactable components can also be provided in more modern production systems.

Zur Vorfixierung der Bürstenhalterung 6 an dem Bürsten-Aufnahmeteil 51 ist die Bürstenhalterung mit Steckfüßen 63, 64 versehen, die hinter korrespondierende Ausnahmen des Bürsten-Aufnahmeteiles 51 einsetzbar sind. Die endgültige Fixierung der Bürstenhalterung 6 erfolgt z.B. mittels Schrauben in Schraubenhalterungen 66 nach der entsprechenden Justierung der Leiterplatte 5 mit Hilfe der in Bürstenführungsöffnungen 61, 62 der Bürstenhalterung 6 eingesetzen Bürsten relativ zum Kommutator 42 des zuvor am Getriebegehäuse 2 montierten Kommutatormotors im Basisgehäuse.To pre-fix the brush holder 6 on the brush receiving part 51, the brush holder is provided with plug-in feet 63, 64, which can be used behind corresponding exceptions of the brush receiving part 51. The final fixation of the brush holder 6 takes place, for example, by means of screws in screw holders 66 after the corresponding adjustment of the printed circuit board 5 with the aid of the brushes inserted in brush guide openings 61, 62 of the brush holder 6 relative to the commutator 42 of the commutator motor previously mounted on the gear housing 2 in the base housing.

Die endgültige Fixierung des Anschlußsteckers 7 erfolgt durch einen Randteil 72 am Steckergehäuse 71, der - wie insbesondere aus FIG 4 bis 6 ersichtlich - in Höhe des oberen Abschlußrandes des topfförmigen Elektronikgehäuses 3 liegt und zwischen dem topfförmigen Elektronikgehäuse 3 und des nach der Montage und Justierung der Leiterplatte 5 auflegbaren Elektronikgehäusedeckels 31 unter Zwischenlage einer Dichtung 32, z.B. durch Anschrauben, fixierbar ist. In vorteilhafter Weise ist - wie insbesondere aus FIG 6 ersichtlich - der Anschlußstecker 7 im Sinne einer toleranzausgleichenden Montage frei schwimmend im Abstand "a" zu den umgebenden Randseiten des Elektronikgehäuses 3 bzw. des Elektronikgehäusedeckels 31 gehalten.The final fixing of the connector 7 is carried out by an edge portion 72 on the connector housing 71, which - as can be seen in particular from FIGS. 4 to 6 - lies at the level of the upper end edge of the pot-shaped electronics housing 3 and between the pot-shaped electronics housing 3 and that after assembly and adjustment of the Printed circuit board 5 electronic housing cover 31 with the interposition of a seal 32, for example can be fixed by screwing on. In an advantageous manner - as can be seen in particular from FIG. 6 - the connector plug 7 is kept floating at a distance "a" from the surrounding edge sides of the electronics housing 3 or the electronics housing cover 31 in the sense of a tolerance-compensating assembly.
